Magnetic Properties of Materials: Detailed Explanation According to Ampere’s law, when current flows through a wire or solenoid then magnetic field is produced around it. The magnetism produced by an atom can be due to 2 types of motion of electrons; spin and orbital motion. The net magnetic field created by the electrons in an [...]
Neodymium Magnet Guide Neodymium Information Collectively known as Rare Earth magnets, Neodymium Iron Boron (NdFeB) and Samarium Cobalt (SmCo) magnets are alloys of the Lanthanide group of elements. Rare Earth magnets are the most advanced commercialized permanent magnet materials today. NdFeB magnets are available in a number of different grades that span a wide range [...]
What are Neodymium Magnets A neodymium magnet are made from an alloy of iron, boron and neodymium. Neodymium magnets are the strongest type of permanent magnet commercially available. What are Magnet Grades? A magnet grade is a measure of the strength of a magnet and in most cases a higher number indicates a stronger magnet. [...]
B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]
Hard And Soft Magnetic Materials Measurements FULL CHARACTERISATIONS OF Hard And Soft Magnetic Materials Measurements - Full characterisation of a vast range of hard and soft magnetic materials, from room temperature to high temperature. In soft ferromagnetic material, we can observe all the magnetic properties even on finished samples, such as rotating machine stators or [...]
Magnetic Losses Reversible Magnetic losses are normal behavior for all magnetic materials. As the remanence of the all the magnetic materials decreases with increasing temperature, the temperature coefficient is negative, it is to be expected that the magnetic field of a magnet also will decrease with an increase of the temperature. However, this decrease of [...]
